Abstract
A process for the regeneration of a coke-contaminated catalytic cracking catalyst removed from a hydrocarbon reaction zone, said catalyst containing catalytically effective amounts of a CO conversion promoter comprising one or more oxides of metals, and for the catalytic conversion of CO, resulting from the oxidation of coke from said catalyst, to carbon monoxide. The process comprises the steps of: oxidizing coke in a first dense bed of catalyst maintained in a regeneration zone to produce partially spent regeneration gas and regenerated catalyst; passing the regeneration gas and regenerated catalyst to a dilute phase transport riser wherein CO is essentially completely converted in the presence of the CU conversion promoter to CO2 and wherein at least a portion of the heat of CO conversion is transferred to the regenerated catalyst; and, passing regenerated catalyst to a second dense bed from which regenerated catalyst is returned to the hydrocarbon reaction zone.
